Perhaps not, or it got lost in the noise about 14 year
old record and Shimano Headsets?

Looks like the black foam lagging a plumber might use when installing
hot water pipes.

It didn't seem different enough from a dozen similar
attempts over the years. It looks like yet another example
of bicycle-related re-invention.

Plus I rarely ride the mountain bike these days.

I've got a mountain bike frame that I use as a utility bike.
I removed the front forks and replaced them with a solid fork
and added drop bars as I find them more comfortable. The most
noticeable difference is that the 1.5 inch tires don't seem
to lose pressure as quickly as a road bile with 23mm tires.

I've converted a number of older rigid frame/forks MTB to drop
bar and bar end shifteres. They make fantastic touring bikes
and tires for them can be bought almost anywhere.

A lot of people like them for riding on dirt roads or roads
with big cracks and potholed pavement.

With brifters a drop bar MTB is the cat's meow.

Cheers

I wonder, after you changed the original telescoping front fork
to solid and add drop bars and brifters, can it still be called a
"MTB" :-?

An aside. The utility bile is all aluminum, frame and forks, and
still weighs more then my all steel road bike :-)


A further aside: One friend of mine left town for employment with
a bike touring company. His job became riding with coast-to-coast
or other long distance riders on his company's tours. He was soon
spending most of his life on the bike.

When one tour came through our area, I was among those who rode out
to meet him again. He was on a very different bike than the
standard road bike he used to use. He was now on a fully suspended
mountain bike frame, but with aero 26" wheels, smooth tires, and
swoopy aero road bars with forearm or elbow resting pads.
Supposedly the frame was extremely expensive, so probably fairly
light. (I don't remember the frame material.)


My mileage is really low this year and so rides that were difficult
are killer now. I was riding what is normally a fairly hard section -
9%-10% and I just couldn't make it to the top without stopping about
100 yards short. Some woman rode past on one of those fat wheel
bikes. She was standing up and pumping.

My heart rate was nearly back to normal so I started again and she
hadn't made it to the top either. I past her and shortly after she
passed me again. And it was a (&(())& electric bike. So they won't
climb without a lot of assistance.


That bugs me sometimes. A few weeks ago I was mashing up a hill and I
have beefy leg muscles. Whoosh ... a young girl on a MTB passed me. When
she was in front I could hear the whirring of the hub motor.
